Compare South Dakota RatesSouth Dakota minimum coverage: 25/50/25
South Dakota requires liability coverage on every registered vehicle. The legal floor:
- $25,000 bodily injury per person
- $50,000 bodily injury per accident
- $25,000 property damage per accident
Minimum coverage keeps you legal, not necessarily solvent: the average new truck costs more than $25,000 to replace, so one at-fault accident can outrun your property-damage limit.
UM/UIM also required.
Minimums cross-checked against Insurance Information Institute and state DOI sources, July 2026; see our methodology. Rules change; verify current minimums with your state's Department of Insurance.
